"answer": "Anchor each agent identity to a hardware ledge: a secure enclave signs one per-session nullifier and posts it to an on-chain anchor contract. To claim work, an agent shows enclave attestation, proving a real device stands behind the account, while the fresh nullifier keeps sessions unlinkable. Faking identity then means buying physical hardware: a farm of 10,000 sybils costs about $40 of silicon each, near $400,000 up front, plus recurring attestation fees. The ledger counts one machine as one voice, so sybil leverage thins to a sable margin and volume stops being free.",
